Ephraim Dawson (died 27 August 1746) was an Anglo-Irish politician.
Dawson was the son of William Dawson and Elizabeth Jardine. He was a successful banker, and used his wealth to purchase an estate at Portarlington, County Laois. In 1713, he was elected as a Member of Parliament for Portarlington in the Irish House of Commons. He represented the seat until 1715, when he was elected to represent Queen's County; he sat for the constituency until his death in 1746.[1]
Dawson married Anne Preston, daughter and heiress of Samuel Preston. He was succeeded by his son, William Dawson, who was created Viscount Carlow in 1776.[2]
